St Thomas' Church is in Warrington Road, Ashton-in-Makerfield, Greater Manchester, England.

It is an active Anglican parish church in the deanery of Wigan, the archdeaconry of Warrington, and the diocese of Liverpool.

The tower has entrances on the north and south sides, and a four-light west window containing Perpendicular tracery.

[2] Removed from the older church are a chandelier, the organ case of 1826, the Royal arms of William IV, and monuments dating back to the 18th century.

Most of the stained glass is by A. L. Moore, including the east window of 1897, which celebrates Queen Victoria's Diamond Jubilee.

[5] The original two-manual pipe organ in the older church was made in 1826 by Bewsher and Fleetwood of Liverpool.
